Flowise

Flowise is a drag-and-drop open-source platform for building LLM agents, chatbots and retrieval workflows, popular for how quickly a working assistant can come together.

Overview

Flowise chains models, memory, tools and vector databases on a visual canvas, with a large library of templates covering customer support, document QA, sales agents and more. Its agent executors support tool use and multi-agent setups, and the whole platform runs locally with a single command.

Beyond prototyping, Flowise provides production features: embeddable chat widgets, API endpoints, credentials management, rate limiting, analytics and agent observability. It supports OpenAI, Anthropic, Google, Azure, AWS Bedrock and local models, and can integrate with LangChain and LlamaIndex components for advanced retrieval. Templates cover common patterns such as document question answering, sales qualification and support triage, so time to first working demo is often under an hour. Community sharing of flows keeps the ecosystem growing quickly.
